What is the 64-KB I/O benchmark performance of Seagate ST500DM002-1BD142 ATA HD?

The I/O performance of reading and writing 64-KB files of a Seagate ST500DM002-1BD142 ATA HD can be measured by running SQLIO with multiple 64-KB blocks with a large stripe factor.

Here is the read performance test of Seagate ST500DM002-1BD142 ATA HD on Azure VM with 64-KB blocks.
